4 Claims. 1

This invention relates to new and useful improvements and structural refinements in gas liquid separating devices, more specifically, to a device of the character herein described, such as may be effectively and conveniently employed in association with oil wells, and the like.

The principal object of the invention is to provide a separating device whereby the oil and the gas usually associated with the same, are separated and delivered to the surface through the medium of independent channels.

A further object of the invention is to provide a separating device which is responsive to the variations of level of the oil in the lower end portion of the well casing, and which therefore, is entirely self-functioning.

Another object of the invention is to provide a separating device which may be readily and conveniently applied to or removed from the well casing.

An additional object of the invention is to provide a separating device which is simple in construction and operation, and which cannot easily become damaged.

A still further object of the invention is to provide a device which may be readily disassembled for purposes of cleaning, inspection or repair.

With the above more important objects in view, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompany ng drawings, in which:

Figure l is a cross-sectional View of the well casing, illustrating the invention in situ therein.

Figure 2 is a cross-sectional view of the invention.

Figure 3 is a further cross-sectional view, taken. in the plane of the line 33 in Figure 2, and

Figure 4 is a cross-sectional view, taken in the plane of the line 4-4 in Figure 2.

Like characters of reference are used to designate parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention embodies in its construction, an elongated, cylindrical jacket 5, the same being configurated substantially as shown and provided at its upper end with an internally threaded adaptor neck 6.

The conventional pump piping 1 is threaded at its lower end into a suitable coupling 8, the latter in turn, being connected to a further length of pipe 9, as is best shown in Figure 2. It will be noted that the adaptor neck 6 is mounted adjacent the coupling 8 at the upper extremity of the pipe 9, and the latter extends to the lower end portion of the jacket 5, for a purpose hereinafter more fully set forth.

A suitable seal or packing N3 is positioned intermediate the ends of the jacket 5 between a pair of retaining flanges H, the seal Ill being in slidable engagement with the inner surface of the conventional well casing l2.

A liquid valve provided with a suitable packing plate or gasket is, is hingedly connected as at it? to the lower end of the pipe 9, whereby the end of the latter may be effectively opened or closed. A gas valve 26 is hingedly connected as at H to the jacket 5, above the aforementioned seal Hi. Both the valve l3 and the valve it are provided with actuating cranks or arms l8, and a valve rod is is pivotally connected at the ends thereof to the two arms, as is best illustrated in the accompanying Figure 2.

A pair of stops, assuming the form of the collars 20, are positioned in a spaced relationship on the valve rod l9, and a float 2| is slidably positioned in the jacket 5. This float is formed with a central bore 22 and with a relatively smaller passage 23, these being adapted to slidably receive the aforementioned pipe 9 and the valve rod 99 respectively. It will be noted that the float 2! engages the portion of the valve rod I9 between the two stops 20.

The lower end portion of the jacket 5 is formed with a plurality of passages or openings 24, these communicating with the interior of the casing l2, below the seal ll].

When the invention is placed in use, the separator as a whole, is lowered to the bottom of the casing It by means of the piping l. The oil in the casing l2 will enter the jacket 5 through the openings 24. and the float 2!, which heretofore has been resting on the lower of the stops 20, will be raised upwardly until it engages the upper stop. This stop and the associated rod 19 will then be lifted in the direction of the arrow 25, thus causing the openings of the valves l3 and It.

The oil in the lower end of the jacket 5 may then enter the pipe 9 and be pumped to the surface through the medium of the piping 1.

Any gas which may have entered the jacket 5 together with the oil, will gather in the upper portion of the jacket and pass into the casing l2 through the valve 16. The gas is then conveyed upwardly through the casing l2, to the ground level. It will be noted that in this tain amount of gas may gather in the upper portion of the jacket 5, this effectively assisting in forcing, so to speak, the oil upwardly through the pipes 9 and I, and thus conserving the gas in the sand. 7

It is believed that the advantages the foregoing disclosure and accordingly, further description thereof at this point is considered unnecessary. a

While in the foregoing there has been shown anddescribed the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

1. A gas-liquid separating device for wells, comprising in combination, a substantially upright well casing, a concentrically disposed jacket provided in said casing and having a closed lower end, an annular seal mounted intermediate the ends of said jacket and frictionally engaging the inner wall of said casing, a concentrically disposed liquid tube positioned in said jacket, the upper end of said jacket being sealed to said tube, a valve at the lower end of said tube, said jacket being formed with passages communicating with the interior of said casing, said passages being disposed above and below said seal, said jacket receiving liquid therein through the lower of said passages, and liquid level responsive means in said jacket for controlling said valve.

2. A gas-liquid separating device for wells comprising in combination, a substantially upright well casing, a concentrically disposed jacket provided in said casing and having a closed lower end, an annular seal mounted intermediate the ends of said jacket and irictionally engaging the inner wall of said casing, a concentrically disposed liquid tube positioned in said jacket, the upper end of said jacket being sealed to said tube, a valve at the lower end of said tube, a further valve in said jacket above said seal, said jacket being formed with passages disposed below said seal, said jacket receiving liquid therein through said passages, and liquid level responsive and use of the invention will be clearly understood from means in said jacket for controlling said valves.
